Riso V8000 What gets me is that it runs fine, I mean I can run 1000 sheets and not miss a beat with a printed sheet. but blank sheets wont run. Is the pick up roller working better because ink is on the paper? If it was a clutch it wouldnt work if it were blank or printed would it? Thanks!!

I took things apart, blew it out and ran test mode and it does run now but I still have the same problem after 50-60 sheets. Before on 11 X 17 I was lucky to get 5 sheets.I took things apart, blew it out and ran test mode and it does run now but I still have the same problem after 50-60 sheets.

Riso's are famous for this, i will scrub the rubber timing
roll with rubber rejuvenator and clean the steel roll with alcohol.The riso
paper feed clutches are weak compared to what they were in this series you may
have to replace the clutch. Bud, after doing some research you need to clean
the oneway bearings on the pickup and feed rolls, adjust feed table hieght and
lastly check/adjust timing in drive and feed roller-you will need a manual for
this.

RZ 220s have a smaller print area on the drum. I think around 9x14. Although the 220s can take 11x17 paper they cannot print over the entire area. (This is why I personally went with a RZ390. It has the 11x17 print area) Sorry, you're out of luck pal.

I've had that problem and running the special blue sheet that comes with the paper pack through the printer seems to work. I've had to run the blue sheet through before each printout for a while, but the problem seems to have gone away - I guess it finally got cleaned out. It also seemed like running the blue sheet through after not using the printer for several weeks was a good idea before printing. When I get a new pack of paper, I run the blue sheet through as instructed. Instead of throwing the sheet away, I store it on top of the blank sheets inside the printer. That way I can use it again if needed.

I assume you are using a sheet of labels, such as the typical 3 x 10 sheet. Word sets up the mail-merge document for printing the whole sheet, so if you print just one or two labels, you will `waste' the rest.One way of using that sheet over is to create a mail merge that contains blank `dummy' addresses. It is rather involved and at best time consuming, and considered not worthwhile to save a partial sheet.I service printers, and personally do not recommend that any label sheet be re-used. The printer curls the paper, in some cases fuses it, and causes the corners of the labels to be exposed, and possibly get caught in the printer (I have removed a lot of labels from inside printers)

get some paper towels and boil some water put in in an old coffee cup. hold the ink cartridges over the water (not in) the steam will clean out the nozzles on the cartridges. the ink will run a lil bit (hence the paper towels) give the printing a go again.

You need to put the test page that was printed into the scanner part of the printer and then press the scan/blue button. This is so the printer can calibrate the new ink. When you have done that the next time you turn on the printer a blank page will not be printed.
When you next change ink you will have to repeat the above procedure.
